77 GHz Millimeter-Wave Radar Blind Spot Warning

The 77 GHz Millimeter-Wave Radar Blind Spot Warning integrates three key safety functions, including BSD (Blind Spot Detection), LCA (Lane Change Assist), and RCW (Rear Collision Warning), helping riders identify hidden risks from the side and rear areas. With a 2Tx+4Rx antenna architecture, high-frequency 77GHz radar technology, and intelligent detection algorithms, the system provides accurate vehicle recognition and stable warning performance.

Designed for two-wheeled vehicle applications, BOSHI radar supports DC 9–16V power input, features ultra-low power consumption of ≤0.8W, and operates reliably in extreme temperatures from -40°C to 85°C. It is suitable for motorcycle manufacturers, electric scooter brands, fleet operators, aftermarket installers, and global automotive accessory distributors.

Why Two-Wheelers Need Millimeter-Wave Radar Protection?

1. Solving Blind Spot Risks Beyond Traditional Mirrors and Cameras

Motorcycles and electric scooters have smaller vehicle dimensions and limited rear visibility compared with passenger cars. Although rearview mirrors provide basic observation, large blind areas still exist on both sides and behind the vehicle. During lane changes, overtaking, and urban traffic congestion, riders may fail to notice rapidly approaching vehicles, resulting in side collisions or dangerous situations.

BOSHI 77 GHz Millimeter-Wave Radar Blind Spot Warning provides an additional safety layer by continuously monitoring surrounding traffic conditions. Instead of relying on the rider’s visual judgment alone, the radar detects approaching vehicles and provides timely warnings to help riders make safer decisions.

2. Radar-Based Detection Provides More Reliable Performance Than Camera Systems

Camera-based blind spot systems depend heavily on visible conditions. Night riding, heavy rain, fog, strong sunlight, and lens contamination may reduce recognition accuracy.

The BOSHI radar system uses 77GHz millimeter-wave sensing technology, which is less affected by environmental visibility. Whether riding during nighttime, rainy weather, tunnels, or high-temperature outdoor environments, the radar maintains stable target detection capability.

For OEM manufacturers and safety solution providers, millimeter-wave radar offers higher reliability for long-term vehicle operation compared with traditional optical monitoring solutions.

Core Technology Advantages

1. 77GHz High-Frequency Radar with 2Tx+4Rx Antenna Architecture

BOSHI 77 GHz Millimeter-Wave Radar Blind Spot Warning adopts a 2-transmit and 4-receive antenna configuration to improve target detection capability and measurement accuracy.

The 77GHz frequency band provides strong anti-interference performance and enables precise recognition of vehicles approaching from different directions. With horizontal and vertical detection angles reaching ±60°, the radar covers a wide surrounding area and reduces blind spots during riding.

This multi-channel radar architecture provides stable sensing performance for motorcycles, electric scooters, and other compact two-wheeled vehicles.

2. High Precision Detection with Real-Time Dynamic Tracking

The radar system provides detection distances of up to 20 meters for two-wheeled vehicles and up to 50 meters for passenger cars. It achieves distance accuracy of 0.2 meters and speed measurement accuracy of 0.5 km/h.

With a 20Hz high-speed data refresh rate, the radar continuously updates surrounding vehicle information during overtaking, lane changing, and fast approaching scenarios. This enables quicker response and reduces warning delays when traffic conditions change rapidly.

3. Low Power Design for Motorcycle Electrical Systems

Designed for two-wheeler electrical architectures, BOSHI radar supports DC 9–16V wide voltage input and maintains average power consumption below 0.8W.

The low-power design minimizes battery load during continuous operation, making it suitable for electric motorcycles, scooters, gasoline motorcycles, and commercial delivery vehicles requiring long-term safety monitoring.

Intelligent Safety Functions

1. BSD Blind Spot Detection for Lane Change Protection

The BSD function monitors the side and rear blind areas of the vehicle. When riding speed reaches 10 km/h or above, the system automatically activates and detects vehicles entering the blind spot range.

When another vehicle appears in the dangerous area, the warning indicator provides a continuous alert, helping riders avoid collisions caused by sudden lane changes or insufficient rear visibility.

This function is especially valuable in urban traffic environments where motorcycles frequently move between lanes.

2. LCA Lane Change Assist for Fast Approaching Vehicles

The LCA function focuses on vehicles approaching quickly from behind. The radar evaluates the approaching speed and distance of rear vehicles and determines potential danger through time-to-collision analysis.

When a vehicle approaches within a dangerous range, the system provides warning signals. If the rider activates the turn signal during a risky lane change situation, the warning intensity increases to remind the rider not to change lanes.

This function helps reduce accidents caused by incorrect judgment of vehicle speed differences.

3. RCW Rear Collision Warning for Rear Impact Prevention

The RCW function continuously monitors vehicles approaching from directly behind. When a rear vehicle closes distance rapidly and creates a collision risk, the system provides an early warning.

This feature is particularly useful for motorcycles and electric scooters that have limited rear protection. It helps riders respond earlier when facing fast-approaching vehicles at intersections, traffic lights, or low-speed riding conditions.

Radar Performance Verification

1. Detection Range and Accuracy Test

BOSHI performs professional radar performance testing to verify detection distance, measurement accuracy, and target recognition capability. During testing, the radar successfully detects two-wheeled vehicles up to 20 meters and passenger vehicles up to 50 meters. The system achieves 0.2-meter ranging accuracy and 0.5 km/h speed measurement accuracy, ensuring reliable identification of approaching targets.

The wide ±60° detection range allows the radar to monitor vehicles from side and rear directions effectively.

2. Algorithm Response and Warning Logic Test

The BSD, LCA, and RCW functions undergo multiple scenario tests, including lane changes, overtaking, same-speed following, and fast rear approach conditions. The BSD system verifies blind spot recognition performance, the LCA system tests warning response during dangerous lane changes, and the RCW system evaluates rear collision warning capability.

Testing confirms that the radar can provide stable warning responses under different traffic conditions while reducing unnecessary alerts.

3. Extreme Environment Reliability Test

The radar is tested under different environmental conditions to ensure long-term reliability. The system operates continuously between -40°C and 85°C without affecting detection accuracy or warning logic. It also maintains stable performance under DC 9–16V voltage fluctuations without restart or communication interruption.

This durability makes BOSHI radar suitable for motorcycles operating in different climates worldwide.
